Generalized Implicit Multi Time Step Integration for Nonlinear Dynamic Analysis

Abstract: Abstract. This paper deals with a generalized multi-time-step integration used for structural dynamic analysis. The proposed method presents three kinds of implicit schemes in which the accelerations and velocities of the previous steps are utilized to integrate the equations of motion. This procedure employs three groups of weighted factors calculated by minimizing the numerical errors of displacement and velocity in Taylor series expansion. Moreover, a comprehensive study on mathematical stability of the pro… Show more
